Super-resolution machining of single crystalline sapphire by femtosecond laser-induced, plasma-assisted ablation
Credit: Opto-Electronic Advances (2024). DOI: 10.29026/oea.2024.240029 A new study in Opto-Electronic Advances discusses super-resolution machining of single crystalline sapphire by GHz burst mode femtosecond laser-induced plasma assisted ablation. GHz burst-mode femtosecond (fs) laser, which emits a series of pulse trains (burst pulse) with extremely short intervals of several hundred ps, offers distinct characteristics in materials
